Title: Improvements in or relating to artificial filaments, films and like materials
IPC: D01F6/60
Filed: 1940-06-21
Abstract: 542,034. Artificial filaments, films etc.; polyamides. DREYFUS, H., MONCRIEFF, R. W., and SAMMONS, C. W. June 21, 1940, No. 10666. [Classes 2 (ii) and 2 (iii)] Artificial filaments, fibres, threads, yarns, films, foils, and like shaped articles are obtained by shaping a solution of a polyamide and setting it in a liquid medium comprising an organic aliphatic compound containing a hydroxyl group directly attached to a carbon atom. The polyamide may be obtained by condensing diamines with dicarboxylic acids or with halides or esters of these acids or by condensing amino-carboxylic acids with themselves or each other. The polyamide may be dissolved in a phenol or carboxylic acid such as formic acid, acetic acid, phenol, cresol, or resorcinol. The hydroxy compound employed in the coagulating medium may be an alcohol such as ethyl, methyl, propyl, or butyl alcohol, or it may be an aliphatic acid such as formic, acetic, propionic, or chloracetic acid. The alcohols may be used in anhydrous condition or diluted with water. The acids should generally be used diluted with water. When aqueous coagulating baths are used the filaments may readily be drawn out to produce filaments of high tenacity and good elasticity. Crinkled filaments may be obtained by allowing the filaments to fall under gravity to the bottom of the setting bath. The filaments may be converted into staple fibres. The films may be used for photographic purposes or for making splinterless glass or glass substitutes. In an example, hexamethylene diammonium adipate is heated with phenol. Adipic acid is added and heating is continued. The product is dissolved in formic acid and purified by precipitation and washing. It is re-dissolved in formic acid and passed from a pressure vessel through a filter of stainless steel gauze and glass wool to a spinning jet. The solution is extruded into a cold aqueous solution of formic acid. Specifications 529,510 and 541,592 are referred to.

Title: Percussion fuzes of great sensitiveness for projectiles
IPC: F42C15/24
Filed: 1939-04-05
Abstract: 540,556. Projectile fuzes. LE GOUPIL, L. B. J. April 5, 1939, No. 10672. [Class 9 (i)] A fuze comprises a body 1 housing a rod-like striker 6 provided with a detachable cap 9, and forwardly urged by a spring 8. A detonator 17 is mounted in a carrier 16 which encloses the paint of the striker and is urged forwards by a spring 19. Normally, the striker 6 is looked by cylindrical segments 20 located between the fuze body and a sleeve 22 on the striker, which sleeve bears at its rear end against a thrust nut 24 on the striker the segments being locked in position by an inertia sleeve 28 supported by a spring 29. The detonater carrier 16 also is normally locked by cylindrical segments 21 bearing against the thrust nut 24 and retained in position by a ring or washer 25. On discharge. the inertia sleeve 28 sets-back against the resistance of the spring 29 and releases the centrifugal segments 20, displacement of which allows the striker 6 to be moved forwards by the spring 8 until arrested by contact of the sleeve 22 with the part 5 of the fuze body. The detonator carrier is caused by a spring 19 to follow the rod 6, until arrested by the washer 25, in which position the segments 21 have passed completely through the washer and are then displaced by centrifugal force. The fuze is thereby armed, and ignition takes place as the result of any impact on the projecting head 9 of the striker. The head may be replaced by a disc screwed and riveted on the rod 6 and of such diameter that it covers the entire front of the fuze. The disc may be covered by a cork or like washer to increase the resistance offered when striking a water surface.

Title: Improvements in or relating to electrical measuring systems for x-ray apparatus
IPC: H05G1/46
Filed: 1943-07-05
Abstract: 564,500. Thermionic valve ammeters and voltmeters ; power meters. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. July 5, 1943, No. 10903. Convention date, July 4, 1942. [Class 37] Means is provided for determining at any moment the thermal condition of an X-ray tube for' the purpose of preventing overloads. A condenser is connected with the X-ray apparatus so as to be charged during exposure periods by a current corresponding to the anode current in order to build up a voltage representative of the anode load, this voltage being measured. A leakage resistance is connected for discharging the condenser in accordance with the cooling rate of the tube so as to simulate the effect of the heat dissipation. The operating alternating current for the X-ray apparatus is supplied through input terminals 10 to an autotransformer 12 which has a switch 13 for selecting a tapping corresponding to the line voltage and switches 14, 15 for coarse and fine adjustment of the anode voltage to be applied to the X-ray tube. The primary 16 of a high voltage transformer 17 is connected to the switches 14, 15 through the contacts 25 of a relay 26 energized through a timing device 27 controlled by a switch 28 so as to select a desired exposure time. The secondary of the transformer 17 contains two coil sections 19, 20 whose mid-point is earthed at 21, a potentiometer resistor 22 being inserted in the earth connection. The X-ray tube 24 is supplied from'the secondary winding through a rectifier 23. The voltage drop between the potentiometer slider 30 and earth 21, which is proportional to the current in the X-ray tube, causes a corresponding current to flow in the anode circuit of a rectifier valve 36 and thereby charge a condenser 50 through resistors 33, 51. A discharge or leakage resistor 60 is connected across the condenser through a valve 61 and simulates the cooling conditions of the X-ray tube, causing a gradual discharge of the condenser in accordance with the declining temperature of the X-ray tube. The voltage across the condenser 50 is a measure of the thermal load condition of the X-ray tube and is determined by means of a valve 70 and milliammeter 80. The grid 71 is used as the anode and operates with a low A.C. voltage. A potentiometer resistance 81 serves for varying the plate voltage during zero adjustment, which is effected when the connection to the condenser 50 is broken by a switch 73 and a resistor 74 connected in the valve circuit. The instrument 80 may be calibrated in heat units. The variable -resistance 33 is adjusted in accordance with the anode voltage of the X-ray tube and may be ganged with the voltage selector 14. The valve 61 blocks the resistor 60 from the discharging circuit during charging periods (exposures) and prevents a voltage division between the resistors 51, 33, 60. During a charging period the voltage drop in the resistor 51 builds up a negative bias on the control grid 64 of the valve 61, thus producing the blocking effect.

Abstract: 296,112. Smith, W. S., Garnett, H. J., and Holden, J. A. April 25, 1927. Alloys. - In a method for the refinement of nickel alloys with a nickel content of not less than 50 per cent and containing one or more of the elements iron, chromium, tungsten, vanadium, molybdenum, silicon, aluminium, copper, cobalt. titanium and zirconium, the furnace is melted in the presence of a slag and hydrogen or other reducing atmosphere in order to avoid the presence of sulphur. The furnace charge consisting of virgin metal with scrap, or entirely of scrap, is melted in a hydrogen or other reducing atmosphere with a suitable slag such as lime with silica and a small amount of fluor spar or calcium chloride. The furnace is preferably of the induction type using low, medium, or high frequency. After fifteen minutes, the sulphur content is very considerably reduced. Hydrogen is then cut off and slag removed. A small amount of oxide of one of the constituents of the alloy or other metals is introduced. The added oxide is allowed to react for a few minutes and then a new slag of suitable materials such as broken glass &c. is added. The metal is then ready to pour. In some cases the metal may be poured after removal of the hydrogen, the resultant bars being remelted as hydrogen is evolved at the first pouring. Finishing agents such as magnesium may be added.
